commit 0c13ed77dd2bc1c2d46db8ef27721213742cccd8 upstream.
DAMON_LRU_SORT handles commit_inputs request inside kdamond thread,
reading the module parameters. If the user updates the module
parameters while the kdamond thread is reading those, races can happen.
To avoid this, the commit_inputs parameter shows whether it is still in
the progress, assuming users wouldn't update parameters in the middle of
the work. Some users might ignore that. Add a warning about the
behavior.
The issue was discovered in [1] by sashiko.

commit 0beba407d4585a15b0dc09f2064b5b3ddcb0e857 upstream.
Patch series "Docs/admin-guide/mm/damon: warn commit_inputs vs other
params race".
Writing 'Y' to the commit_inputs parameter of DAMON_RECLAIM and
DAMON_LRU_SORT, and writing other parameters before the commit_inputs
request is completely processed can cause race conditions. While the
consequence can be bad, the documentation is not clearly describing that.
Add clear warnings.
The issue was discovered [1,2] by sashiko.

Pull RISC-V updates from Paul Walmsley:
"Before v7.0 is released, fix a few issues with the CFI patchset,
merged earlier in v7.0-rc, that primarily affect interfaces to
non-kernel code:
- Improve the prctl() interface for per-task indirect branch landing
pad control to expand abbreviations and to resemble the speculation
control prctl() interface
- Expand the "LP" and "SS" abbreviations in the ptrace uapi header
file to "branch landing pad" and "shadow stack", to improve
readability
- Fix a typo in a CFI-related macro name in the ptrace uapi header
file
- Ensure that the indirect branch tracking state and shadow stack
state are unlocked immediately after an exec() on the new task so
that libc subsequently can control it
- While working in this area, clean up the kernel-internal,

"The largest part here are devicetree fixes for Qualcomm, and NXP i.MX,
addressing a few regressions and incorrect settings in board and SoC

The largest single commits are a revert of a cleanup patch for i.MX
that caused regressions for the NAND flash controller and a fixup for
an incomplete cleanup of the PCIe controller on Qualcomm platforms
that broke because the state was left incompatible with both the old

On the Rockchips, Hisilicon, Renesas, Allwinner and AT91 platforms,
only a single simple dts bugfix each was added since the last round of

"Here are a bunch of USB and Thunderbolt fixes (most all are USB) for

partly due to my recent travels, and partly due to people banging away
on the USB gadget interfaces and apis more than normal (big shoutout
to Android for getting the vendors to actually work upstream on this,
that's a huge win overall for everyone here)
Included in here are:
- Small thunderbolt fix
- new USB serial driver ids added
- typec driver fixes
- gadget driver fixes for some disconnect issues
- other usb gadget driver fixes for reported problems with binding
and unbinding devices as happens when a gadget device connects /
disconnects from a system it is plugged into (or it switches device
mode at a user's request, these things are complex little
beasts...)
- usb offload fixes (where USB audio tunnels through the controller
while the main CPU is asleep) for when EMP spikes hit the system
causing disconnects to happen (as often happens with static
electricity in the winter months). This has been much reported by
at least one vendor, and resolves the issues they have been seeing
with this codepath. Can't wait for the "formal methods are the
answer!" people to try to model that one properly...

Per Linus' comments requesting the replacement of "INDIR_BR_LP" in the
indirect branch tracking prctl()s with something more readable, and
suggesting the use of the speculation control prctl()s as an exemplar,
reimplement the prctl()s and related constants that control per-task
forward-edge control flow integrity.
This primarily involves two changes. First, the prctls are
restructured to resemble the style of the speculative execution
workaround control prctls PR_{GET,SET}_SPECULATION_CTRL, to make them
easier to extend in the future. Second, the "indir_br_lp" abbrevation
is expanded to "branch_landing_pads" to be less telegraphic. The
kselftest and documentation is adjusted accordingly.

In previous patch "Documentation: clarify the mandatory and desirable

checks. One is "get_maintainers.pl" (no 's' in the script name), and the
other one is a missing closing quote after "Reported-by", which didn't
have effect here but I don't know if it can break rendering elsewhere
(e.g. on the public HTML page). Better fix it before it gets merged.

The PTP clock for the Tegra234 MGBE device is incorrectly named
'ptp-ref' and should be 'ptp_ref'. This is causing the following
warning to be observed on Tegra234 platforms that use this device:
ERR KERN tegra-mgbe 6800000.ethernet eth0: Invalid PTP clock rate
WARNING KERN tegra-mgbe 6800000.ethernet eth0: PTP init failed
Although this constitutes an ABI breakage in the binding for this
device, PTP support has clearly never worked and so fix this now
so we can correct the device-tree for this device. Note that the
MGBE driver still supports the legacy 'ptp-ref' clock name and so
older/existing device-trees will still work, but given that this
is not the correct name, there is no point to advertise this in the
binding.

adopted by distros and get exposed to many new workloads. We made a
sub-smart move of making a behavior change in v6.12 which could
impact performance, without making it opt-in. Fixing this mistake
retroactively, to be picked by LTS.

Commit 7d6899fb69d25 ("ovl: fsync after metadata copy-up") was done to
fix durability of overlayfs copy up on an upper filesystem which does
not enforce ordering on storing of metadata changes (e.g. ubifs).
In an earlier revision of the regressing commit by Lei Lv, the metadata
fsync behavior was opt-in via a new "fsync=strict" mount option.
We were hoping that the opt-in mount option could be avoided, so the
change was only made to depend on metacopy=off, in the hope of not
hurting performance of metadata heavy workloads, which are more likely
to be using metacopy=on.
This hope was proven wrong by a performance regression report from Google
COS workload after upgrade to kernel 6.12.
This is an adaptation of Lei's original "fsync=strict" mount option
to the existing upstream code.
The new mount option is mutually exclusive with the "volatile" mount
option, so the latter is now an alias to the "fsync=volatile" mount
option.

Jihed Chaibi <jihed.chaibi.dev@gmail.com> says:
adau1372_set_power() had two related error handling issues in its enable
path: clk_prepare_enable() was called but its return value discarded, and
adau1372_enable_pll() was a void function that silently swallowed lock
failures, leaving mclk enabled and adau1372->enabled set to true despite
the device being in a broken state.
Patch 1 fixes the unchecked clk_prepare_enable() by making
adau1372_set_power() return int and propagating the error.
Patch 2 converts adau1372_enable_pll() to return int and adds a full
unwind in adau1372_set_power() if PLL lock fails, reversing the regcache,
GPIO power-down, and clock state.

The adm1177 driver exposes the current alert threshold through
hwmon_curr_max_alarm. This violates the hwmon sysfs ABI, where
*_alarm attributes are read-only status flags and writable thresholds
must use currN_max.
The driver also stores the threshold internally in microamps, while
currN_max is defined in milliamps. Convert the threshold accordingly
on both the read and write paths.
Widen the cached threshold and related calculations to 64 bits so
that small shunt resistor values do not cause truncation or overflow.
Also use 64-bit arithmetic for the mA/uA conversions, clamp writes
to the range the hardware can represent, and propagate failures from
adm1177_write_alert_thr() instead of silently ignoring them.
Update the hwmon documentation to reflect the attribute rename and
the correct units returned by the driver.

temperature
The hwmon sysfs ABI expects tempN_crit_hyst to report the temperature at
which the critical condition clears, not the hysteresis delta from the
critical limit.
The peci cputemp driver currently returns tjmax - tcontrol for
crit_hyst_type, which is the hysteresis margin rather than the
corresponding absolute temperature.
Return tcontrol directly, and update the documentation accordingly.

The prefix/header of a TLP that caused an error may be recorded in the AER
Capability and emitted to the kernel log in raw hex format. Document the
existence and usage of tlp-tool, which decodes the TLP Header into
human-readable form.
The TLP Header hints at the root cause of an error, yet is often ignored
because of its seeming opaqueness. Instead, PCIe errors are frequently
worked around by a change in the kernel without fully understanding the
actual source of the problem. With more documentation on available tools
we'll hopefully come up with better solutions.
There are also wireshark dissectors for TLPs, but it seems they expect a
complete TLP, not just the header, and they cannot grok the hex format
emitted by the kernel directly. tlp-tool appears to be the most cut and
dried solution out there.

We look up a netdev during prep of Netlink ops (pre- callbacks)
and take a ref to it. Then later in the body of the callback
we take its lock or RCU which are the actual protections.
The netdev may get unregistered in between the time we take
the ref and the time we lock it. We may allocate the hierarchy
after flush has already run, which would lead to a leak.
Take the instance lock in pre- already, this saves us from the race
and removes the need for dedicated lock/unlock callbacks completely.
After all, if there's any chance of write happening concurrently
with the flush - we're back to leaking the hierarchy.
We may take the lock for devices which don't support shapers but
we're only dealing with SET operations here, not taking the lock
would be optimizing for an error case.

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.
ARM:
- Correctly handle deactivation of interrupts that were activated
from LRs. Since EOIcount only denotes deactivation of interrupts
that are not present in an LR, start EOIcount deactivation walk
*after* the last irq that made it into an LR
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when pKVM
is already enabled -- not only thhis isn't possible (pKVM will
reject the call), but it is also useless: this can only happen for
a CPU that has already booted once, and the capability will not
change
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was
exposed by the recent conversion to kmalloc_obj(); rip out all the
ugliness that led to the wart
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR
access, float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in
kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked
as available whenever the kernel used scattered feature words for
them
- Validate _all_ GVAs, rather than just the first GVA, when
processing a range of GVAs for Hyper-V's TLB flush hypercalls
- Fix a brown paper bug in add_atomic_switch_msr()
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel
local APIC (and AVIC is enabled at the module level)
- Update CR8 write interception when AVIC is (de)activated, to fix a
bug where the guest can run in perpetuity with the CR8 intercept
enabled
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to
allow L1 hypervisors to set FREEZE_IN_SMM. This reverts (by
default) an unintentional tightening of userspace ABI in 6.17, and
provides some amount of backwards compatibility with hypervisors
who want to freeze PMCs on VM-Entry
- Validate the VMCS/VMCB on return to a nested guest from SMM,
because either userspace or the guest could stash invalid values in
memory and trigger the processor's consistency checks
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from
being unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite
being rather unintuitive
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd
selftest to 64 (from 8)"

Pull USB fixes from Greg KH:
"Here is a large chunk of USB driver fixes for 7.0-rc4. Included in
here are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc
driver bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next
with no reported issues. That one came in too late, and is 'obviously
correct' :)"
